Applicatibn filed September 13, 1918.

To all whom it may concern:

Be it known that I, JAMns F. ASTLEY, a citizen of the United States,residing at Pawtucket, in the county of Providence and State of lthodeIsland, have invented a new and useful Shuttle-Smash Preventer, of whichthe following is a specification.

The present invention relates to shuttle smash preventers, and aims toprovide a novel and improved appliance of that charactor.

The present invention is of value in an automatic weft-replenishingloom, and it is the object of the invention to provide Sl1'l1 ple yeteffective means applicable to a weftreplenishing loom and operable forpressing into place an improperly placed bobbin for preventing a shuttlewith an improperly placed bobbin entering the shed from the shuttle boxat the magazine end. Thus, if the transferrer of the automatic loomfails to position the bobbin properly in the shuttle at the time ofreplenishment, the bobbin is moved into place within the shuttle beforethe shuttle enters the shed by the present device.

The invention is illustrated in the accompanying drawing, wherein z-Figure l is an elevation of the device as applied to the lay and shuttlebox of a loom. 2 is a perspective view of the attach ment, portionsbeing broken away.

In the drawing, there is illustrated a lay 1 having upon one end thereofthe usual shuttle box 2 for receiving the shuttle S. Mounted above theshuttle box 2 at the magazine end is an automatic weft-replenishing orfilling supplying mechanism 3 of ordinary construction, and onlyillustrated diagrammatically, a bobbin being transferred from themagazine into the shuttle at the time of replenishment in the ordinarymanner, and it is the object of the present invention to provide meansfor pressing the bobbin into the shuttle if the bobbin is not properlyplaced in the shuttle by the transferrer (not shown).

The present attachment embodies a standard 4'supported in any suitablemanner in rear of the lay 1 and having a bracket 5 below thelay to whicha lever 6 is fulcrumed between its ends. An eccentric or cam 7Specification of Letters Patent.

bears upon one arm of said lever and is carried by a shaft 8 which canbe operated timely by any suitable mechanism, said shaft being readilyconnected to the operating mechanism of the loom as will be apparent tothose skilled in the art. The other arm of the lever 6 is connected by avertical'link 9 with an lL-shaped lever 10 having one arm fulcrumedbetween its ends to the upper end of the standard 4; adjacent and inrear of the lay and shuttle box. The fulcrum of the lever 10 isindicated at 11, and the other arm of said lever extends across the layadjacent the mouth of the shuttle box, the lower edge of the arm 12being cut on a compound curve to cooperate properly with the shuttle andits bobbin. The lever 10 is oscillated properly through the medium ofthe cam or eccentric 7 which oscillates the lever 6, whereby the arm 12is moved downwardly to operative position when the shuttle leaves theshuttle box, and the arm 12 is moved upwardly when the shuttle entersthe shuttle box. The device is arranged to operate, either by gravity orspring tension, to tend to assume the dotted line position in Fig. 1,when the cam 7 is moved upwardly. The preventer is thus operated to movethe arm 12 thereof downwardly when the shuttle leaves the shuttle box,and this will prevent the shuttle from entering the shed should thebobbin of the shuttle be improperly placed.

lVhat is claimed is:

The combination with the lay of a loom, of a smash preventer embodyingan L-shaped member one arm of which forms a lever pivotally mountedadjacent the lay, the other arm of the L-shaped member extending acrossthe lay to move up and down and to press down an improperly placedbobbin into a shuttle passing under said member, and means foroscillating said member to move the second mentioned arm thereof to andfrom the lay.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
